So the Michelin 325/25/20 that some of us need remains on backorder (many months now) Well, Pirelli is making some - thats great-but three tire shops could not get that tire to "seat" on my Champion wheels-despite trying for 2+ hrs each place (Braman Porsche, Champion Porsche, and Lamborghini of West Palm) So we sent them back to Tire Rack. Anyone else having mounting problems with this batch of Pirelli tires?!? Or know the secret...thanks
